capacitance
意味: The ability of a component or circuit to store electrical charge, measured in farads. A capacitor with high capacitance stores more charge at a given voltage.
Capacitance is one of the three fundamental passive electrical properties alongside resistance and inductance. Capacitors — devices designed to store charge — are ubiquitous in electronic circuits, used for filtering, timing, energy storage, and power smoothing. In touchscreen technology, the human finger alters the local capacitance of the screen surface, enabling touch detection.
例文
- The capacitance of the smoothing capacitor was chosen to minimise voltage ripple in the power supply. 平滑电容器的电容值经过选择,以最大限度地减少电源中的电压纹波。La capacitancia del condensador de filtrado fue elegida para minimizar el rizado de tensión en la fuente de alimentación.電源の電圧リプルを最小化するために、平滑コンデンサの静電容量が選定された。전원 공급 장치의 전압 리플을 최소화하기 위해 평활 커패시터의 정전용량이 선정되었다.
- Touchscreens work by detecting changes in capacitance caused by the proximity of a conductive object such as a fingertip. 触摸屏通过检测导电物体(如指尖)接近时引起的电容变化来工作。Las pantallas táctiles funcionan detectando los cambios de capacitancia provocados por la proximidad de un objeto conductor como la yema de un dedo.タッチスクリーンは、指先などの導電性物体の接近によって生じる静電容量の変化を検出することで動作する。터치스크린은 손끝과 같은 전도성 물체의 접근으로 인한 정전용량의 변화를 감지하여 작동한다.
- The physics students measured the capacitance of a parallel-plate capacitor and observed how it varied with plate separation. 物理课学生测量了平行板电容器的电容,并观察了它如何随极板间距变化。Los estudiantes de física midieron la capacitancia de un condensador de placas paralelas y observaron cómo variaba con la separación entre placas.物理学の学生たちは平行板コンデンサの静電容量を測定し、極板間の距離によってそれがどう変化するかを観察した。물리학과 학생들은 평행판 커패시터의 정전용량을 측정하고, 극판 간 거리에 따라 그것이 어떻게 변하는지 관찰했다.

起源と歴史
From Latin capacitas (ability to hold), derived from capax (capable of holding). The electrical sense was coined in the late 19th century as the theory of electrical circuits was formalised.
